Chapter 4.3A, Problem 8A

To determine

(a)

To find:

The $\text{LCM}\left(a,b\right)$. If $\text{GCD}\left(a,b\right)=1$, where, a and b are natural numbers.

To determine

(b)

To find:

The $\text{GCD}\left(a,a\right)$ and, $\text{LCM}\left(a,a\right)$, where, a and b are natural numbers.

To determine

(c)

The $\text{GCD}\left(a^2,a\right)$ and, $\text{LCM}\left(a^2,a\right)$, where, a and b are natural numbers.

To determine

(d)

To find:

The $\text{GCD}\left(a,b\right)$ and $\text{LCM}\left(a,b\right)$. If $a|b$, where, a and b are natural numbers.
